All the colors of the rainbow! A full coverage of emission wavelengths in the visible region (405–616 nm) with large Stokes shifts in C3‐Indo‐Fluor may be straightforwardly and succinctly achieved by the palladium‐catalyzed direct CH arylation of indolizines at the C3 position of the pyrrole ring (see figure). The fluorophores have successfully marked A375 cells.
